Installing the Cisco NCS 4201
Connecting a Management Ethernet Cable
When using the Ethernet Management port in the default mode (speed-auto and duplex-auto) the port operates
in the auto-MDI/MDI-X mode. The port automatically provides the correct signal connectivity through the
Auto-MDI/MDI-X feature. The port automatically senses a crossover or straight-through cable and adapts to
it.
However, when the Ethernet Management port is configured to a fixed speed (10, 100, or 1000 Mbps) through
command-line interface (CLI) commands, the port is forced to the MDI mode.
When in a fixed-speed configuration and MDI mode:
• Use a crossover cable to connect to an MDI port
• Use a straight-through cable to connect to an MDI-X port
To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,
Warning
connect the Management Ethernet ports only to intra-building or unexposed wiring or cable. The
intrabuilding cable must be shielded and the shield must be grounded at both ends. The intra-building
port(s) of the equipment or subassembly must not be metallically connected to interfaces that connect to
the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or
Type 4 ports as described in GR-1089-CORE) and require isolation from the exposed OSP cabling. The
addition of Primary Protectors is not sufficient protection in order to connect these interfaces metallically
to OSP wiring. Statement
Installing and Removing SFP and SFP+ Modules
The Cisco NCS 4201 supports a variety of SFP and SFP+ modules, including optical and Ethernet modules.
For information on how to install and remove SFP and SFP+ modules, see the documentation for the SFP or
SFP+ module at:
For information about inspecting and cleaning fiber-optic connections, see:
for Fiber-Optic
We recommend that you wait for 30 seconds between the removal and insertion of an SFP on an interface
Caution
module. We recommend this to allow the transceiver software to initialize and synchronize with the Cisco
NCS 4201. Changing an SFP quicker could result in transceiver initialization issues that disable the SFP.
Connecting a USB Flash Device
To connect a USB flash device to the Cisco NCS 4201, insert the memory stick in the USB port labeled USB
MEM. The Flash memory module can be inserted only one way, and can be inserted or removed regardless
of whether the chassis is powered up or not.
